Seaweed has been a superfood since prehistoric times
Seaweed is often regarded as a superfood, celebrated for its health advantages and sustainability. There are approximately 10,000 different species of seaweeds in the world, however only 145 species are eaten today.
According to a new study, our European forebears were already consuming this nutrient-rich plant for thousands of years into prehistory.
Researchers from the University of York and the University of Glasgow, claim to have found “definitive” archaeological evidence that seaweeds and freshwater plants have been consumed from as early as the Mesolithic, through the Neolithic transition, and into the Early Middle Ages.
According to the study, published in Nature Communications, evidence of seaweed being a food source is rarely recorded, and is normally considered for non-edible uses such as fuel or fertiliser.
A team of archaeologists conducted an analysis of biomarkers derived from dental calculus obtained from 74 individuals across 28 archaeological sites, spanning from northern Scotland to southern Spain. Their investigation unveiled “direct evidence for widespread consumption of seaweed and submerged aquatic and freshwater plants.”
Samples with surviving biomolecular evidence revealed consumption of red, green or brown seaweeds, or freshwater aquatic plants, with one sample from Orkney also containing evidence for a Brassica, most likely sea kale.
Karen Hardy, Professor of Prehistoric Archaeology at the University of Glasgow said: “Today, seaweed and freshwater aquatic plants are virtually absent from traditional, western diets and their marginalisation as they gradually changed from food to famine resources and animal fodder, probably occurred over a long period of time, as has also been detected elsewhere with some plants.
“Our study also highlights the potential for rediscovery of alternative, local, sustainable food resources that may contribute to addressing the negative health and environmental effects of over-dependence on a small number of mass-produced agricultural products that is a dominant feature of much of today’s western diet, and indeed the global long-distance food supply more generally.”

Archaeologists from the University of Warwick are conducting an underwater study to document the submerged Mesolithic site of Bouldnor Cliff before it vanishes due to erosion.
Bouldnor Cliff is situated in the Solent between the Isle of Wight and the southern coast of England. The site was first discovered in 1999 when divers observed a lobster discarding worked flint tools from its burrow on the seabed.
At a time when Britain was cut off from mainland Europe by rising sea levels, the area of the Solent was a river valley inhabited by an advanced Mesolithic community who developed a boat building technology 2,000 years ahead of their time.
The study aims to find new data on the nature of the late Ice Age environment during the development of the Mesolithic era, and the extent of the interaction between the inhabitants of Bouldnor Cliff and Europe, including the exchange of materials.
Professor Robin Allaby, who is leading the expedition, said: “This is an incredible opportunity to understand the lost world in which the Mesolithic developed using the latest techniques before our chance is gone.”
The study will involve a comprehensive palaeoenvironmental analysis, in addition to state-of-the-art techniques such as optical simulated luminescence for constructing ecological profiles. Furthermore, archaeologists intend to recover archaeological artefacts and environmental markers to reconstruct the past environment.
Dr Kinnaird adds: “This is an exciting research project to showcase the new innovations in luminescence dating, which can tell when an object was last exposed to the Sun. The relevance of this technique in writing the narratives for 4000 years of history, at the time that the British coastline was rapidly changing, is huge!”
According to the researchers, these discoveries carry the potential to significantly transform our comprehension of the era when Britain emerged as an island.

A study of the “Excalibur” sword found in Valencia has been revealed to have Islamic origins sometime during the 10th century AD.
Valencia is one of the oldest cities in Spain, founded under the name of Valentia Edetanorum by the Romans in 138 BC.
The city was conquered by the Moors in the 8th century AD, and was destroyed by Abd al-Rahman I of the Umayyad dynasty. Under Caliphate rule, the wider city area became known as Madînat al-Turâb (meaning “city of earth” or “sand”).
The sword was discovered back in 1994 in a house on Valencia’s Historiador Chabàs Street, where it was found standing upright in a grave beneath an Islamic era house.
Dubbed “Excalibur” due to the circumstances of its discovery, the sword is made from iron and has a hilt decorated with bronze plates. In mythology, Excalibur was the legendary sword of King Arthur and appears in various medieval poems describing Arthur pulling the sword from a stone.
However, the “Excalibur” from Valencia was found in a sedimentary strata from the 10th century AD and was likely the weapon of a cavalryman from the Andalusian Caliphate Era.
According to the archaeologists, the sword measures 46 centimetres in length and has a slightly curved blade towards the tip. Swords from this period are rarely found well-preserved due to the levels of oxygen and water in the soil that causes oxidation of the iron.
“It is the first Islamic sword that appears in the city of Valencia, with only one similar example being found during the excavations of Medina Azahara, the caliphal city of Abd al-Rahman III, in Córdoba,” said the Valencia City Council.
